Preheat the oven to 350F and grease and line a 9" round springform pan.

Whisk together the flour, baking powder, and salt in a medium bowl and set aside.

In a large mixing bowl, whisk together the butter and sugar. Add the egg, vanilla, lemon zest, and lemon juice and mix to combine.

Add the dry ingredients and mix until smooth.

Spread the thick batter evenly in the bottom of the springform pan. Set aside.

In a mixing bowl using a hand or stand mixer with the whisk attachment, mix the cream cheese until smooth.

Mix in the powdered sugar, one cup at a time, until thin and creamy.

Then mix in the egg and lemon zest.

Pour the cream on top of the lemon batter, allowing it to naturally spread close to the edges.

Bake for 35-40 minutes, or until the top has formed a golden skin and it’s evenly puffed.

Allow the cake to cool at room temperature for about 30 minutes, then transfer to the refrigerator and chill uncovered for about 2 hours.

Run a knife around the edge of the pan and release the cake. Top with powdered sugar then slice and enjoy!
